Gravitational waves will settle cosmic conundrum
Feb 15, 2019 (SPX)
The cosmos has been expanding for 13.8 billion years and its present rate of expansion, known as the Hubble constant, gives the time elapsed since the Big Bang....
New squeezing record at GEO600 gravitational-wave detector
Dec 17, 2018 (SPX)
These cause a background noise which overlaps with gravitational-wave signals. This noise is always present and can never be entirely removed. But one can chang...
Mini-detectors for the gigantic
Dec 13, 2018 (SPX)
As early as 1916 Albert Einstein submitted an article to the Prussian Academy of Sciences, in which he demonstrated that moving masses such as giant stars orbit...
Portsmouth researchers make vital contribution to new gravitational wave discoveries
Dec 04, 2018 (SPX)
The new results are from the National Science Foundation's LIGO (Laser Interferometer Gravitational-Wave Observatory) and the European-based VIRGO gravitational...
Four New Gravitational Wave Detections Announced
Dec 03, 2018 (SPX)
Professor Sheila Rowan is Director of the University of Glasgow's Institute for Gravitational Research. Professor Rowan said: "This remarkable crop of detection...
Universal laws in impact dynamics of dust agglomerates under microgravity conditions
Nov 19, 2018 (SPX)
In particular, their response when hit by projectiles is key because the conditions causing impact-induced sticking, bouncing, fracturing, and so on, must be kn...
Griffith precision measurement takes it to the limit
Nov 06, 2018 (SPX)
Published in Nature Communications, the work saw the Griffith team, led by Professor Geoff Pryde, working with photons (single particles of light) and using the...
In five -10 years, gravitational waves could accurately measure universe's expansion
Oct 24, 2018 (SPX)
Pinning down the exact rate of expansion, called the Hubble constant after famed astronomer and UChicago alumnus Edwin Hubble, has been surprisingly difficult. ...
Gravitational waves could shed light on dark matter
Oct 24, 2018 (SPX)
Gravitational waves passing through will distort the sides of the triangle slightly, and these minimal distortions can be detected by laser beams connecting the...
Kin of gravitational wave source discovered
Oct 17, 2018 (SPX)
The newly described object, named GRB150101B, was reported as a gamma-ray burst localized by NASA's Neil Gehrels Swift Observatory in 2015. Follow-up observatio...
RUDN physicist described the shape of a wormhole
Oct 17, 2018 (SPX)
Modern concepts of the Universe provide for the existence of wormholes - unusual curvatures in space and time. One can imagine a wormhole as a black hole throug...
RUDN mathematicians confirmed the possibility of data transfer via gravitational waves
Oct 15, 2018 (SPX)
It turned out that there is the possibility of transmitting information with the help of nonmetricity waves and transferring it spatially without distortions. T...
GRACE-FO Satellite Switching to Backup Instrument Processing Unit
Sep 17, 2018 (JPL)
A month after launching this past May, GRACE-FO produced its first preliminary gravity field map. The mission has not acquired science data since mid-July due t...
Boosting gravitational wave detectors with quantum tricks
Sep 07, 2018 (SPX)
Gravitational wave detectors are extremely sensitive and can e.g. register colliding neutron stars in space. Yet even higher sensitivity is sought for in order ...
Household phenomenon observed by Leonardo da Vinci finally explained
Aug 09, 2018 (SPX)
Famous inventor and painter Leonardo da Vinci documented the phenomenon, now known as a hydraulic jump, back in the 1500s. Hydraulic jumps are harmless in our h...
GRAVITY Confirms Predictions of General Relativity Near Galactic Center
Jul 27, 2018 (SPX)
These results were obtained by the GRAVITY consortium, led by the Max Planck Institute for Extraterrestrial Physics (MPE) in Germany and also involving the CNRS...
How to weigh stars with gravitational lensing
Jul 24, 2018 (SPX)
Light from this background star must cross the gravitational field of the foreground star where, instead of following straight paths, the light rays are bent. T...
Could Gravitational Waves Reveal How Fast Our Universe Is Expanding?
Jul 12, 2018 (SPX)
Astronomers have pointed telescopes to certain stars and other cosmic sources to measure their distance from Earth and how fast they are moving away from us - t...
Einstein's Theory of Gravity Still Passes the Test
Jul 05, 2018 (SPX)
A hammer and a feather fall with the same acceleration on the Moon. And a light cannon ball hits the ground at the same time as a heavy cannon ball when dropped...
VLT makes most precise test of Einstein's general relativity outside Milky Way
Jun 25, 2018 (SPX)
Collett explains "We used data from the Very Large Telescope in Chile to measure how fast the stars were moving in ESO 325-G004 - this allowed us to infer how m...
